SAP connection state

0 No SAP connection established.

1 SAP connection ongoing, i.e. peers exchange messages.

Notes

• If AT^SRSA with <dataForm> set to 1 (SAP) is given on the same serial multiplex channel as specified with

parameter <muxChan> the SAP data transfer mode is entered immediately. Therefore no command response

is issued by the TC63 in this case.

• If the TC63 is acting as SAP client and has switched to a remote SIM it starts accessing this SIM. If during

this time AT commands are used which need access to the SIM itself (e.g. AT+CPIN?) the TC63 responds

with "+CME ERROR: SIM blocked" or "+CME ERROR: SIM busy". Retry until SIM is fully accessible in this

case.

• If the TC63 is acting as SAP server and has released its SIM to a client it considers it as not accessible. There-

fore AT commands which require SIM access will be rejected with "+CME ERROR: SIM not inserted".

• Parameters <muxChan>, <dataForm> and <beaconPer> are applicable for RSA activation only.
